The Spirit 23 K is a nimble and engaging sailboat designed by the American maritime architect Robert Finch, first introduced in 1978. Built by Spirit Yachts, a subsidiary of the renowned powerboat manufacturer Glastron in Austin, Texas, this 23-foot masthead sloop carved a niche as a capable and trailerable cruiser. Renowned for its lively performance and practical layout, the Spirit 23 K offers an appealing blend of recreational cruising comfort and surprising speed, making it a valuable resource for both aspiring and experienced sailors.

History and Design

The Spirit 23 K emerged from a lineage that began with the North American 23, produced from 1976 to 1978. When powerboat giant Glastron acquired North American Yachts, the sailboat line was rebranded, and the North American 23 evolved into the Spirit 23 and its "K" variant. Robert Finch's design philosophy for this model aimed to create a small cruiser that was both practical and offered respectable sailing characteristics.

While Glastron was primarily known for its mass-produced fiberglass powerboats, which pioneered innovations like the SSV hull, their foray into sailboats with the Spirit line represented a less typical offering, with the tooling for these boats acquired from another company. The Spirit 23 K stands out from its counterpart, the Spirit 23, by featuring a lead fin keel, a taller mast, a larger sail area, and a midship traveler, all contributing to its enhanced performance. Additionally, the Spirit 23 series, including the 23 K, was available with an optional lifting "pop-top" coach roof, significantly increasing interior headroom when raised. Production of the Spirit 23 K continued until 1981.

Sailing Performance and Handling

With a sail area to displacement ratio (SA/D) of approximately 18.22, the Spirit 23 K exhibits good potential for performance in lighter winds, indicating a boat that can get moving easily. Its ballast to displacement ratio (B/D) of around 36.5% suggests moderate stiffness, allowing it to stand up to a decent breeze without excessive heeling. Furthermore, a displacement to length ratio (D/L) of approximately 175.78 places the Spirit 23 K in the lighter, more performance-oriented category for its size, rather than a heavy, traditional cruiser.

Owners frequently describe the Spirit 23 K as a "very fast" sailboat for its class, capable of reaching hull speeds of nearly 6 knots. It is noted for its ability to handle various sea states effectively, with one owner remarking that it "doesn't fear the sea." Its design contributes to an "easy to handle" nature, making it manageable even for single-handed sailing. The combination of its fin keel and masthead sloop rig contributes to a balanced and responsive feel at the helm.

Accommodations and Layout

The interior of the Spirit 23 K, while compact, is generally considered practical, especially for its size as a small trailerable cruiser. The standard cabin provides a maximum headroom of 4.75 feet. However, a significant enhancement was the optional "pop-top" roof, which when raised, expanded the interior headroom to a more comfortable 6.17 feet, greatly improving liveability at anchor or dock.

Typical interior arrangements for boats of this size usually include a V-berth forward, a compact galley area, and a small salon space with settees that may convert into additional berths. While specific details on the finish quality and materials are not extensively documented, period Glastron boats were known for fiberglass construction, implying a functional and durable interior, often featuring basic wood trim. Owners have noted the interior is functional, though original components may show their age. Effective ventilation would likely depend on the presence of the pop-top and any deck hatches or ports.

Owner's Perspectives

Owners of the Spirit 23 K often praise its lively sailing characteristics, describing it as "very fast," "comfortable," "safe," and even "beautiful." Its solid construction is frequently highlighted, providing a sense of security even in challenging conditions, with many appreciating that it "doesn't fear the sea." The boat's ease of handling is also a recurring positive, making it an accessible option for various skill levels. Many find the interior to be "very practical," suitable for weekend trips or small family outings, particularly with the added headroom of the pop-top.

While generally well-regarded, some owners have noted common maintenance points. A recurring issue can be the tendency for original deck fittings to develop leaks over time, requiring re-bedding to ensure a dry interior. However, with routine maintenance, the Spirit 23 K continues to be a cherished "great little boat" with a loyal following, as evidenced by active owner communities on sailing forums.
